ADJUSTABLE MOUNTING FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 595,180, dated December7, 1897.

Application filed March 11, 1897. Serial No. 627,040. (No model.)

described and claimed and illustrated in theaccompanying drawings, madea part of this application, has reference to certain new and usefulimprovements in mechanism for. mounting sliding doors for residences andall other kinds of buildings where such a door is desirable. I

The object of my invention is to provide an adjustable track which willpermit the door to freely travel from one end to the other thereofwithout obstruction or binding.

Another object of myinvention is to render it possible for any person,whether a skilled mechanic or not, to so adjust the track thatcompensation will be easily made for any settling of the partition orother walls of the building, thus preventing the door from becomingsagged at one side and the binding or wedged condition incident thereto.

\Vith the foregoing objects in view attention is called to the drawings,in which- Figure 1 is a side elevation of my invention as applied to theinner side of one row of studding. Fig. 2 is avertical section thereofon line a a. Fig. 3 is a perspective view of the yoke.

plate and hooks. Fig. 5 is a detail of adjusting-seat for threadedshaft.

Reference will be had to various details by figures, 1 indicating theinner surface of one row of studding, to the outer surface of which lathand plaster are secured in the usual manner.

At a convenient point above the door I secure to one of the studding theplate 2, having attached thereto the journal 3, upon which is pivotedthe lever 4. To the outer end of the lever 4 I pivotally attach thesupportingshaft 5, designed to extend downward to the outer end of thetrack 6, to which it is adjustably secured by means of the nuts 7. T othe inner end of the lever 4 I pivotally attach Fig. 4: is a detail ofthe retaining the adjusting-loop 8, designed to receive the threaded endof the shaft 9, the lower end of which terminates in the squareadjustingpoint 10, which extends entirely through the track. The otherend of the track is adjustably supported by the threaded shaft 11,formed substantially the same as shaft 9, the upper end thereof beingseated in the threaded loop 12, formed substantially the same as loop 8.The shafts 9 and 11 are made with right and left screw-threads, so thatwhen a tool is applied to the square end 10 of either shaft the trackmay be easily and quickly raised or lowered. The square end 10 is alwaysaccessible, and this form of construction is more preferable than whenthe rods Sand 11 have the same hand-thread with nuts on the same justabove and below the track for its adjustment. This latter form ofconstruction is preferable for the right-hand screw-rod No. 5. This rod,carrying a nut 7, passes loosely through the strap or angle iron 15 andtakes in a threaded nut on the under side of the upper surface 6 of thetrack. This end of the track is at the outset adjusted in position'by'inanipulating the nut 7 and the nut on the under side of the track.The supports 9 and 11 could be connected to the track in the same wayand be adjusted in the same manner, but it is preferred to serew-threadthe straps l5 and dispense altogether with the nuts above and below thetrack. Both of these supports being just above the door or in thedoorway can be easily reached ud readily adjusted. It will be evidentthat the purpose of the lever 4 and attachments is to permittheadjustment or the end of the track, supported by the rod5, which isboth out of sight and out of reach, through the right and left threadedrod 9. of the track is adjusted by the right and left screw-support 11.All these supports pass loosely through the top of the track, wherebysufficient play isallowed to avoid rigidity and any binding action ofthe parts. The straps 15 are pivoted to the side bars of the track byscrews, as shown, or by any other suitable means. Said loop 12 ispivotally attached at its upper end to the journal 13, rigidly securedand held in position by the 'retaining-plate 14, attached at aconvenient The other end will occupy a true horizontalplane, whichangle-irons 15, soformed that they will extend across the top of thetrack a d upon each sideu thereof, where -ithey are he d by screwsorother'suitable means.

- the mid 6f fins-amen e.

. As-will be seen in Fig. 1, I prefer to provide a pair of wheels foreach side" of the door or for each part thereof which it may :be

deemed necessary to support. Said wheels 16 are connectedv rigidly to anaxle 17 of sufficient length to permit each wheel to rest upon -tions"2l in order that it and the supportingwheels may be easily removedand replaced inretltting or. repairing the supportiug do yices ofthedoor.

form' connection with the hooks 22-, integrally formed with the plate23,01- otherwise attached thereto. I tached'directly to the upper edgeof the door after the same has been properly trimmed ready for assumingits operative position by means of the retaining-s'crewsfi-t, as shown.

The object in providing a hook which shall be-rigidly attached to thedoor is to enable the door to ,be readily disengaged from thesupporting-yoke when it may be necessary to gain accessto the trackorother parts.

The operation of my invention may be.

stated to be as followsthat is to say, the track is adjustablysuspendedin position overthe opening forming the proposed door. This location ofthe track is preferably done during the process of constructing thewalls.

The several pairs of wheels are mounted upon the track and provided withan individual yoke, the ends of. which extend slightly below the trackproper, but not far enough to protrude beyond the line of the proposedfinish.- After these parts have thus been assembled the .track maybe soadjusted that it adjustment is, effected by a suitable wrench adapt-edto act upon the square ends of the threaded shafts." If, for instance,the outer endof the lever 4 should hold its end of the track higher thanthe other end, a true adj ustment may be readily effected. by properlyrowill be understood, extend sufficiently far to properly receive or Thesaid plate is designed to be attating the threaded shafts Qandll, thesame action-being taken should said lever hold its end of the tracklower than the opposite end. After the track has thusbeen truly adjustednor, are ready to be hung in position after The complete finish'may thenbe added. If at any time thereafter it is found that the track needsreadjustment-to hooked from the yoke, as it will be understood that theline of finish shall not prevent the door being moved laterallysufficientlyto efiect such disengagement. a

Believing that the advantages, construction, and operation of myinvention will be made fully apparent by the foregoing specification andthe accompanying drawings further description is deemed unnecessary.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1.- In a'sliding door, a track for the same, pivoted, screw-threadedloops, and threadedbolts connecting the loops and the track foradjusting the track, as set forth.

2-. In a s 1 id ing door, a track for the door, pivoted loops, and adjusting devices connected directly to the loops and attached to thetrack, as set forth.

3.--In sliding doors, a adjustable supports at each end of the track,one of the supports consisting of a pivoted lever havinga loop carryinga screw-bolt pivbolt at the other end, as set forth.

4. In sliding doors, .a track provided with pivoted loop-supports androllers, said supports including a pivoted lever carrying adto. thetrack, as set forth. 5. In sliding doors, a track adjustablysups-i'sting of a pivoted lever carrying a pivoted screw-bolt at one endand a pivoted loop at the other end carrying a screw-bolt, and deas setforth. v p 1 a 6. In sliding doors, a track, pivoted loops carrying adjusting devices connected to the track, as set forth. I

7. In sliding doors, a track having screwthreaded attachments, pivotedsupports consisting in part of screw-threaded links, and screw-boltseonnectin g the links'and the track, all combined as set forth.

In testimony whereof I affix my signature in presence oftwo witnesses.
